New owner here. I bought a 2002 vel satis with 2.0T and 6-speed last week, and there is one problem that I can't find any information on. So, when my car idles, there's this "rolling marbles" sound, which goes away as I depress clutch. At first I thought that it was either throw-out bearing or main shaft bearing, but now I definetly can say that that not it, or at least not only it. Today I noticed – when I switch on AC "marbles" start rolling really hard, like two-three times louder. And if I turn steering wheel while AC is on, sound goes from "rolling marbles" to "self-destructing diesel engine". However,the strangest part of it all is the fact that noise goes away with depressed clutch too. Oh, and engine also makes weird metallic tapping noise on switch off whith engaged clutch, which I attribute to possible nearing dmf failure. So, my question – is it throw-out bearing, input shaft bearing, dmf, shot clutch, or is it something else?
Edit: And yes, just noticed that I submitted it in wrong place, really sorry about that.
